SELF-HEATING SAD-IRON.

Application filed May 31, 1913.

Specification of Letters Patent.

Patented Apr. 7, 191e.

serial No. 770,984.

To all whom it may concern Be it known that I, DANIEL W. YOUNG, Jr., acitizen of the United States, and a resident of the city of Chicago,county of Cook, and State of Illinois, have invented certain new anduseful Improvements in Self-Heating Sad-Irons, of which the following isa specification.

My invention relates to improvements in self heating sad-irons and hasparticular reference to that class thereof designed for use wherekerosene is used as the fuel.

The object of my invention is the production of a sad-iron as mentionedwhich will be of durable and economical construction and efficient inuse.

Other objects will appear hereinafter.

The invention consists in the combinations and arrangements of partshereinafter described and claimed.

rlhe invention will be best understood by reference to the accompanyingdrawings forming a part of this specification, and in which- Figure l isa central vertical section of a sad-iron embodying my invention, Fig. 2is a horizontal section taken on substantially line w-w of Fig. l, Fig.3 is a vertical transverse section taken on substantially line m-m ofFig. l, Fig. l is an enlarged vertical section taken on substantiallyline y-fy of Fig. 2, Fig. 5 is an enlarged detail section taken on linez--e of Fig. 2, Fig. 6 is an enlarged bottom plan view of the cover ofthe body of the iron, Fig. 7 is an enlarged front elevation of a fittingused in the connection of the drain pipe of the fuel tank with thegenerator of the iron, and Fig. 8 is a perspective view of the outer endof said drain pipe of the fuel tank which engages with the fitting shownin Fig. 7.

The preferred form of construction as illustrated in the drawingscomprises a hollow body l of usual form, open at its upper side.Arranged within the body l in superposed relation are the generator 2and the burner 3, the latter being of course arranged below the former.The burner 3 is supported in operative position by means of a dependingarm 4t provided at the inner end of the generator 2, the arm l embracingthe lower end of a substantially U-shaped pipe section 5 which serves inthe capacity of a mixing chamber, one end of the burner 3 being threadedinto the corresponding end of the member 5, the latter in turn beingsecured to the supporting arm 4 by means of a set screw 5. The upper endof the member 5 is spaced from the discharging orifice of the generator2 in order to effect a thorough mixing of the gas issuing from saidorifice before reaching the burner 3.

The outer end of the generator 2 is provided with an enlargement 6,rectangular in form, which snugly 'fits a slot 7 of corresponding formprovided in the upper edge of the rear wall of the iron. The lateraledges of the enlargement 6 are of channel form, as shown, for embracingthe adjacent edges of said slot whereby said generator and hence th'eburner and mixing chamber are supported in operative position. The loweredge of the enlargement 6 is provided with depending pointed projections8 which engage notches 9 provided in the bottom of the slot 7, thisconstruction serving to securely hold said enlargement 6 in position inthe slot 7 preventing free movement.

The burner 3 is provided at its under and upper sides with spacedtransversely eX- tending slits l0 and ll respectively through which thefuel escapes for combustion. The openings l0 are larger than theopenings ll in order to permit of escape of a greater amount of gas tosupport a primary flame for the heating of the bottom of the iron largerthan that which will be supported at the upper side of the burner forheating the generator 2 in the generation of the liquid fuel into gas.The upper side of the bottom of the iron body is hollowed out slightlyto conform substantially with the formation of the burner, and vided ateither side of the burner, arranged in alinement with the openings 10thereof which serve as obstructions to prevent spreading of the jetsinto engagement with the lateral walls of the iron. Without theprovision of obstructions as mentioned the flame at the under side ofthe burner spreads over the entire bottom of the iron and impingesagainst the lateral walls of the body of the iron, considerable fuelbeing thus wasted in the heating of said walls. With the presentconstruction, the flame will be confined to the bottom or operativeportion of the iron body and thus economy in fuel effected.

Arranged at the reaward end of the iron at one side thereof is the fueltank l2 provided with a filling plug 13 of ordinary construction.Leading from the bottom of the projections 12 are protank 12 is the fueloutlet pipe 14 the outer or lower end of which is connected with anipple 15 formed at the rearward end of the generator 2. Said end ofsaid outlet pipe is connected with the nipple 15 through the med-ium ofa fitting 16, one end of which is threaded into said nipple, the end ofsaid outlet pipe loosely fitting in said fitting as clearly shown inFig. 4. At the extremity of the pipe 14 are provided diametric ears orlugs 17 which engage recesses 17 provided in the member 16, which serveto lock the pipe 14 against relative rotary movement in said member 16and hence to maintain the tank 12 in upright position. Snugly fittingthe pipe 14 adjacent the end thereof is a tapering' collar 18 adapted toengage a Y seat 19 formed in the member 16: Loosely mounted upon saidpipe 14 is a screw cap 20 adapted for threaded engagement with the outerend of fitting 16. The cap 2O engages against the outer end of thecollar 18 serving to force the latter into secure engagement with theseat 19, the latter in turn pressing said collar into close engagementwith ythe pipe 14, whereby an absolutely tight joint is effected withoutthe use of packing such as is now generally used. The bottom of the cap20 which engages against the outer end of collar 18 is beveled, asshown, inorder to also press said end into close engagement with thepipe 14, when said cap is threaded into the member 16 to operativeposition.

The flow of fuel to the generator is governed by a valve 21 which isthreaded in the outer end of said generator, an exteriorly g positionedhand wheel 22 being provided for operating said valve. VThe inner end ofsaid valve `is adapted for engagement with a seat 23, as clearly shownin Figs. 1 and 2, the same being adapted, when in engagement with saidseat, to shut ofi' the supply of fuel to the generator.

Secured to the inner end of the valve 21 and extending coaxiallytherewith is a rod or stem 24 hexagonal in form which snugly fits thepassage 25 through the generator. With this arrangement it will be seenthat the passage through the generator will be divided into apluralityof smaller passages segmental in cross-section which register with thefaces or sides of the member 24, it being clear that the edges of saidmember 24 engaging against the sides of the passage 25 result in thisdivision. The formation of a plurality of narrow passages through thegenerator, results in the division of the fuel introduced into thegenerator into as many thin streams ,which of course may be more readilyheated than one solid stream, vthereby facilitating the generatingprocess. This arrangement is further of advantage in that the passagethrough the generator, with this construction, will be continually tionsto this kind of an iron.

it will be seen that detachment operation or rotation of Upon rotationof the valve the member 24 will rub against'the sides of the passage 25and thereby effect dislodging of any particles or carbon which mightotherwise clog said passage, the clogging of the passage through thegenerator of a sad-iron of this nature, through carbon-` ization, beingone of the lgreatest objec- VVth the present construction this objectionwill be overcome and without any extraieffort on the part of theoperator, the cleaning being cleaned through the valve. edges of thedone simultaneously with the operation of Y the valve. The member 24 maybe cleaned occasionally by removing the Vvalve 21,"said member 24 beingcarried thereby. The inember 24 is of such a length as to projectthrough the discharge vorifice of the generator, when the valveis inclosed position in order to dislodge any foreign matter which might clogsaid orifice.Y The outer end of said member 24 however does not seatagainst the contracted end'of the passage 25, the latter that uponvclosing which is left in therefrom.

of the valve 21 any fuel said passage may escape The upper side of thebody 1 is closed by a cover 26 which is provided with a suitable handle27. Said cover is releasably locked to the body 1, at its front end, bymeans of lingers 28 provided at the under side of said coverwhich engagenotches 29 provided in the upper edges of the lateral walls of saidbody. A depending lug 30 provided at-theV front end of the cover 26 isadapted to fit snugly in the vertex of the iron between the lateralwalls thereof to prevent relative lateral movement of the cover when inopera,- tive position. The rearward end of said cover is secured inposition by means of a thumb screw 31 which is threaded in one of thelateral walls of the body 1, the head of said screw engaging a notch 32provided in the adjacent end of the cover. The edge of the notch 32 andthe base portion of the head of screw 31 are beveled so as to insure asnug engagement and conduce to a secure fastening of the cover to thebody. A lug 33 provided at the rearward end of the cover is adapted toengage against the rearwall of the body l to prevent movement of thecover in one direction, lateral movement thereof in theoppositedirection being of course prevented by screw 31. With this arrangementof the cover may be effected upon retraction of the screw 31.

Provided at the underside of the cover 26 is a transversely arched.,deflector plate 34 which is spaced slightly from said cover as clearlyshown in Figs. 1 and 3. The plate 34 serves to deiect the heated gasesarising from the burner through lateral ventilation always remainingopen soV openings which are provided at the opposite sides of the ironby cutting away the upper edge portions of the lateral walls of the bodyl, thereby serving to prevent heating of the handle 27. By spacing thedeflector plate 34 from the cover, cool air may circulate between saidparts from one side of the iron to the other and thus serve in a senseto insulate the handle from the heated portion of the iron.

A sad-iron of the construction set forth will be found effectual in use,the same may be readily cleaned and may be manufactured at a low cost.

While I have illustrated and described the preferred form ofconstruction for carrying my invention into effect, this is capable ofvariation and modification without departing from the spirit of theinvention. I, therefore, do not wish to be limited to the precisedetails of construction set forth, but desire to avail myself of suchvariations and modifications as come within the scope of the appendedclaims.
